Research shows that enhancing communication and partnership among patients, parents, and providers is especially critical for optimal outcomes in pediatric diabetes. Communication gaps and conflict can complicate the already complex provider-patient interactions and daily management. We have therefore designed, refined, and made available to consumers a new mobile-based intervention, CareCoach, to improve communication; build trust among providers, patients and parents; and increase overall satisfaction with the quality of diabetes care. This web/mobile application is designed to help patients unobtrusively audiorecord their clinical encounters, track their medical consults and treatment plans, review information from past visits, create visit discussion guides, and track adherence to medication and dosing schedules. In addition, because mobile-based applications are inexpensive to administer, portable, and available at all times of day, CareCoach holds great promise for communication coaching and contributing to improved diabetes management.
